Even Paris Hilton's ex-boyfriend doesn't want to be associated with "Greasy Bear" Brandon Davis. The oil heir reportedly showed up to the Details mag party last week in Hollywood and was outraged to be denied entry. Davis "started demanding that staffers get Stavros [Niarchos]," says an insider. When Niarchos heard the tale, he begged staffers to tell Davis he wasn't there, adding, "I didn't invite him here, and I don't really want to be around him." Davis was eventually allowed in after kicking up a fuss, and Niarchos apologized to a Details editor, saying, "You know I would never bring him here."
